Emil Warburg
Emil Gabriel Warburg (; 9 March 1846 – 28 July 1931) was a German physicist who during his career was professor of physics at the Universities of Strassburg, Freiburg and Berlin. He was president of the Deutsche Physikalische Gesellschaft 1899–1905. His name is notably associated with the Warburg element of electrochemistry. Among his students were James Franck (Nobel Prize in Physics, 1925), Eduard Grüneisen, Robert Pohl, Erich Regener and Hans von Euler-Chelpin (Nobel Prize in Chemistry, 1929). He carried out research in the areas of kinetic theory of gases, electrical conductivity, gas discharges, heat radiation, ferromagnetism and photochemistry. He was a member of the Warburg family, and the father of Otto Heinrich Warburg (Nobel Prize in Physiology, 1931). He was a friend of Albert Einstein.

Altona, Hamburg
Altona (), also called Hamburg-Altona, is the westernmost urban borough (''Bezirk'') of the German city state of Hamburg, on the right bank of the Elbe river. From 1640 to 1864, Altona was under the administration of the Danish monarchy. Altona was an independent borough until 1937. In 2016 the population was 270,263. History Altona was founded in 1535 as a village of fishermen in what was then Holstein-Pinneberg. In 1640, Altona came under Danish rule as part of Holstein-Glückstadt, and in 1664 was granted municipal rights by the Danish King Frederik III, who then ruled in personal union as Duke of Holstein. Altona was one of the Danish monarchy's most important harbor towns. The railroad from Altona to Kiel, the Hamburg-Altona–Kiel railway ( da, link=no, Christian VIII Østersø Jernbane), was opened in 1844. Because of severe restrictions on the number of Jews allowed to live in Hamburg until 1864 (with the exception of 1811–1815), a major Jewish community develop ...

Deutsche Physikalische Gesellschaft
The German Physical Society (German: , DPG) is the oldest organisation of physicists. The DPG's worldwide membership is cited as 60,547, as of 2019, making it the largest physics society in the world. It holds an annual conference () and multiple spring conferences (), which are held at various locations and along topical subjects of given sections of the DPG. The DPG serves the fields of pure and applied physics. Main aims are to bring its members and all physicists living in Germany closer together, represent their entirety outwards as well as foster the exchange of ideas between its members and foreign colleagues. The DPG binds itself and its members to advocate for freedom, tolerance, veracity and dignity in science and to be aware about the fact that the people working in science are responsible to a particularly high extent for the configuration of the overall human activity. Conferences and fostering young talent The DPG itself does not carry out any research, but its confer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German Lutherans
The religion of Protestantism, a form of Christianity, was founded within Germany in the 16th-century Reformation. It was formed as a new direction from some Roman Catholic principles. It was led initially by Martin Luther and later by John Calvin. History The Protestant Reformation began with the publication of the ''Ninety-five Theses'' by Augustinian monk Martin Luther in 1517. The key element of this religious upheaval was a break from Roman Catholicism's emphasis on tradition, favouring a focus on the Bible. The lasting effects of Luther's Protestant movement within Germany was to question its existing power structures, imploring lay nobles for church reformation, critiquing the Roman mass, sacraments and seeking to reaffirm the importance of faith in good works. His subsequent excommunication from the Church ensured Germany had an ideological divide between Protestant sects and other Christian denominations. Another prominent reformer, Martin Bucer, introduced the rite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnetic Refrigeration
Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ranges used in common refrigerators. A magnetocaloric material warms up when a magnetic field is applied. The warming is due to changes in the internal state of the material releasing heat. When the magnetic field is removed, the material returns to its original state, reabsorbing the heat, and returning to original temperature. To achieve refrigeration, the material is allowed to radiate away its heat while in the magnetized hot state. Removing the magnetism, the material then cools to ''below'' its original temperature. The effect was first observed in 1881 by a German physicist Emil Warburg, followed by French physicist P. Weiss and Swiss physicist A. Piccard in 1917. The fundamental principle was suggested by P. Debye (1926) and W. Giauque (1927). The first working magnetic refrigerators were constructed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Warburg Family
The Warburg family is a prominent German and American banking family of German Jewish and originally Venetian Jewish descent, noted for their varied accomplishments in biochemistry, botany, political activism, economics, investment banking, law, physics, classical music, art history, pharmacology, physiology, finance, private equity and philanthropy. They are thought to have originated as the Venetian Jewish del Banco family, Anselmo and Abraham Ha Levi Kahana de Palenzuela from Spain, one of the wealthiest Sephardic German families in the early 16th century. Due to restrictions limiting Jewish involvement in banking, they moved to Bologna, and thence to Warburg, in Germany, in the 16th century, after which they later took their name. The first known ancestor was Simon von Kassel (1500 - 1566). The family later established itself in Altona, near Hamburg in the 17th century, after the Thirty Years' War, and it was in Hamburg that M. M. Warburg & Co. was established in 1798, among ...
